Step-by-step explanation:
2x-3y= -14
5x+9y= -2
multiply the first one by 5 and the second one by -2 to get equal and opposite value of x.
➡️when you multiply,it will be
10x-15y= -70
-10x-18y= 4
cancel out each x value,then you get
-15y-18y= -70+4
-33y= -66, divide each side by -33 to get the value of y
⚪️y= 2
➡️substitute the value of y in the equation of (2x-3y= -14) to find the value of x
2x-3(2)= -14
2x-6= -14
2x= -14+6
2x= -8 divide both side by 2
⚪️x= -4
so the answer is (-4,2)
Answer:
64

B
my way of answer this is just have to have per because you're dealing with unit rates :)
Answer:
D) 2852$
Step-by-step explanation:
basically you just multiply what the dude bought by how much money he spent, so
18 saws * 16$ = 1224 $
22 drills * 74$ = 1628$
then you add that together
1224 + 1628 = 2852$
